Options

A. Newtons
B. Calories
C. Joules
D. Both (b) and (c)

Explanation

To solve the question about the units of energy that you read on a food label, we can follow these steps:

### Step 1: Understand the Question
The question asks for the units of energy that are typically found on food labels. We need to identify which units are used to measure energy in food.

**Hint:** Think about the common terms you see on food packaging related to energy.

### Step 2: Identify Possible Units of Energy
We need to consider various units of energy. The common units of energy include:
- Joules (J)
- Calories (cal)
- Newtons (N)

**Hint:** Remember that Newtons are not a unit of energy but a unit of force.

### Step 3: Analyze Each Unit
- **Newtons (N)**: This is a unit of force, not energy. Therefore, it cannot be the correct answer.
- **Calories (cal)**: This is a unit of energy commonly used in the context of food. It measures the amount of energy that food provides when consumed.
- **Joules (J)**: This is the SI unit of energy. While it can be used to measure energy in food, it is less common on food labels compared to calories.

**Hint:** Consider which unit is more frequently mentioned in dietary contexts.

### Step 4: Determine the Most Common Unit on Food Labels
In general, food labels primarily use calories to indicate the energy content of food. While joules can also represent energy, calories are the standard unit used in dietary contexts.

**Hint:** Think about how often you hear people discussing their calorie intake compared to joules.

### Step 5: Conclusion
The units of energy that you read on a food label are primarily **calories**.

**Final Answer:** Calories
